Be it known thrt LMABX FINSTONE, n citizen oil the United States ofAmerica, re siding atB-oohlyn, Kin s County, State of New York, haveinvente certain :new anti useful lmprovenients in Fountein-Pens 'ofwhich the foliowing is e full, clear, anti exact description.

. This invention reietes to improvments in fountein-pens of theseif-fiiiing variety` 'One oj: the objects oi? my invention is toprovide e mechenism 'which can be nienipuiteci enterioriy of the 'herreiof the pen to conipress e seek or reservoir within the harroi to filithe seine with inh. t My invention reiates particuieriy to the nie-unsfor cmpresing the sach, seid secks being weil known expedients in thisarit One of the advantages of my improveddevice is that it can besiipped into barrei and heici therein without re- .sorting to screws,rivets or any 'fastening element requiring the boring of hoies whichweekens the barrei of the pen.

I will now proceeci to escrihe iny invention in deta'h the n'ovelfeatures of which win he ponted out in the ciains, reference -bein hadto the eccom en in drwin forming part hereof, wherein-' Figura 1 isri-side eievetion, partly in-sec' tion ofa seitfiiling fountain penembodying my improvement;

Fg. 2 is 'an enlarged fregmentary cross setionel View, the section beingtaken on a. iinc 2-2 in Fig. l;

"Fig". 3 is en enlerged fragmentury longitudinei sectionei View,iliustreting the sachcompr'essinghevice es pesitioneci to con1- pressthe sak; and

Fig. 4 is' a cieteii perspective view of one of the sach conpressingelements.

As herein embodied, my .improvement eomprises a ciepressible ber 5,preferahiy yieideble, .carrying at one end thereof e stirrup 6 toreceive the inner' end 7 of e, compressible seek 8. f the bar 5 I secureat one end thercof as at), e yieldabie auxiliary ber or V carrier 10which et it's free end-is pivotaily connected to a lever ll, the innerend 12 of which rests upon the her 5. The opposite end 13 of seid leveris erranged to be pulled upwerdiy ta Swing the lever il upon its pivot14: to depress the hair 5, as nchcated 111 Fig. 3. The auxiiiery har 10is preferehly Secured to the mein or ciepressihle bar 5 adja cent thestirrup 6; hence when the iever il is manipnleted, to depress the innerend 'thereoi", the main her 5 will yieid or bend inwardiy es shown bydotted linos in Fig. l.

in order to depress the ber`5 the auxiliary bar 10 must be held againsten Upward movement to form' a temporarily stationery support for thepivot point for the iever 11. To acccinplish thisresult, I form the har10 as indicate& in Fig. 4. In other words, the bur 10 consists of afletstrip 15 `having e 'rib 16 throughout a portion of its crun-menberand the 'reeeud of the ber 10 Wii rise until the sidesviigs 20 of theban '10 contact with the weil of the burrel 21, as

indicated in F 3,'afterwhich the mein bar 5 will be depressed and;compress the sack 8 to exclude aiifrom within for the purpose offilling same with ink when said seek i's ailowed to expznd or resume itsnatural shape. The first part of the operation of depressing the har 5wiil be to Swing the bei' 10 upwardiy until the side wings strike thebarrel of the pen. A eontinued movement of the level' ll will depressthe bar 5. The mein bar 5 and euxiiiary char 10 are preferabiypenmnnently Secured together, the lever 11 being pcrnanently pivoteliysecured to the her -103 hence the entire suck compressing mechanism canbe assenbled and placed within the birrei 'of a pen without forning anyopenings, excepting the slot 19 to receive' the ieve'r lll After thedepressing mechnnism is inserted the suck 8 (one end of which is secure&to the pensection22) can be slipped into piece.

It will be' seen in Figs. 2 and 3 that the lever il, is chenneiedlongtudineily so as to .fit over 01' straddle the rib 16 of the bar 10connected to said depressible bar, said supporting element beingprovided With an upstanding longitudinal rib and side-Wings arranged tocontact with the in'ner surface of said barrcl When said lever ismanipulatod to depress said bar, all of said sack compressing elementsbeing unsecured to said barrel.

2. sack conpressing device for fountanpens; consisting of a depressiblebar, a earrior Secured thereto at one end thereof, a

. longitrdinally disposed upstanding rib on said carrier, a levorpivotaily connected internediatc its ends to the free end of the icarrier said lever being channeled longitudinally to straddle the rib onthe carrier, one end of said lever being arranged to slid-- ably bearagainst said bar When'the opposite Signed at -New York city, N.
